I’m trying to rotate two objects by scrolling horizontally. The scrolling is controlled by the mousemovement. When the pointer goes right, the objects rotate left, and the other way round. The faster the mouse moves, the more the object rotates.
When the mouse pointer stops for 30ms I want the object to commute slowly with a keyframe that is defined by the current mouse/scroll-speed.
The rotation during the scrolling works fine, but when I added the keyFrame-Function to commute the object, it all went weird.
It starts to rotate after I stop the mouse and it rotates up to 3 times and not in the shortest way.
Maybe someone knows why that is and how to dissolve this problem?
